Re: Adding and Subtracting Polynomials

I think the problem is that the apparent minus sign is actually an 'em dash', which MIF's LaTeX can't interpret (but Codecogs displays it as if it were a minus sign).

When composing in M$ Word, a minus sign is automatically replaced by an em dash after typing a space followed by a minus sign followed by a space and some other entry. So I wonder if SlowlyFading's composition was in a word processor, not a LaTeX editor. That problem doesn't arise when typing directly into MIF's message box.

With the em dash in I get:

#17:

#19:

Using a minus sign instead of the em dash gives:

#17:

#19:

Composing in M$ Word without using a space on both sides of the minus sign displays correctly.

Also, when typing directly into MIF's message box the display is the same with and without spaces before and after the plus and minus signs.

Re: Adding and Subtracting Polynomials

Hi Bobby,

If you click on SlowlyFading's #19 you'll see the different dash lengths between "2 - x" and "x - 4". #17 doesn't have that comparison, but you can see the dash is longer than usual...like in #19's "2 - x".

Re: Adding and Subtracting Polynomials

Thanks all of you!

I can't see the "." in the original post, but I can see the difference in the lengths of the dashes, theminus vs the m dash. I do my encoding with "Post reply" on MIF so I guess that's why I haven't nadany problems with it.

Thanks again!

SlowlyFading, did you see the difference in the two dashes?

Writing "pretty" math (two dimensional) is easier to read and grasp than LaTex (one dimensional).LaTex is like painting on many strips of paper and then stacking them to see what picture they make.

Re: Adding and Subtracting Polynomials

I get a û when I enter alt 150. On mine this does not render in latex at all. Did you mean alt 95?

Hi phrontister;

I'd thought that maybe there was a fly-spot on your screen, or that you wore binocular specs and had them on back-to-front!

I killed those flies about a month ago. Yes, I got both of them. The question is, to dot or not to dot. Post #37 shows an actual, in living color snapshot of my screen. The dot according to my computer is a real phenomena and not an apparition.

I always believed that you saw it, but not necessarily that it was there!

It is true that my dopamine and/or serotonin levels have been dropping over the last few months but why would that make my computer see dots?

In mathematics, you don't understand things. You just get used to them.If it ain't broke, fix it until it is. Always satisfy the Prime Directive of getting the right answer above all else.

Hi bobbym

the alt+150 isn't necessarily the same character as the ASCII 150 character.

Re: Adding and Subtracting Polynomials

No, that is what would cqlm you down. I think it needs a circuit masaage.

Re: Adding and Subtracting Polynomials

Did you try the first 31?

Either way, searching through the table, I found that the short and the long dash are 45 and 196 respectively.

Re: Adding and Subtracting Polynomials

Just asking. Did you see my suggestion of a circuit massage for your computer?
